I-IOYT W. CHASE, OF INDIANAPOLIS, INDIANA, ASSIGNOR 0F ONE-FOURTH TO CLARA EUGENIA KERR, OF INDIANAPOLIS, INDIANA.

ELECTRICAL HEATER.

T 0 all whom it may concern:

Be it known that I, Herr W. CHASE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Electrical Heatcl's o-f-wlTic'IT ho-following is a specification, reference being had to th e accompanying drawings.

This invention relates to certain improvements in electrical heaters and it is an object of the invention to provide a novel and improved device of this eneral character especially designed-and a aptegfijor use in connection with hand wheels and iflo'ie particular] to a wheel comprised in a steering lTlBChfinlSlll of an automobile, aeroplane or other conveyance.

It is also an object of the invention t rovide a novel and improved device of his general character which may readily and conveniently be engaged with the rim of a wheel in such a position as grasped by the hand.

The invention also has for an object to provide a. novel and improved electric heater which may he applied=to the rim of a steering wheel or the like without the necessity of changing the whcel'in any way. r

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved electnc heater wherein certain 1 portant advantages are attained and the'de' vice rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hcrema fter more fully set The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood I will now proceed to describe the same with reference to the accompanying drawings wherein F1 re 1 is a view in perspective of a steering wheel having heaters applied thereto constructed in accordance with an embodiment of my invention;

Fig. 2 is a fragmentary view in side elevation of a steering wheel showing the heater as herein embodied applied thereto;

Fig. 3 is a fragmentary view in side ele vation of the rim of a wheel and of the heater applied thereto;

Specification of Letters Patent.

to be directly the same above and below the rim Patented Mar. 26, 1918.

1917. Serial No. 152.043.

Fig. 4 is an enlarged fragmentary view partly in plan and partly in longitudinal section illustrating certain details of my improved heater as herein disclosed;

Fig. 5 is a sectional view taken substantially on the line 5-5 of Fig. 4; A

Fig. 6 is a fragmentary view partly in elevation and part1 in longitudinal section illustrating additional details of my improved heater;

Fig. 7 is a fragmentary view partly in transverse section and partly in elevation of my improved heater with portions omitted' and l ig. 8 is a diagrammatic view disclosing certain features of my invention as herein set forth.

As disclosed inthe accompanying drawings R denotes the rim of "a conventional type of steerin wheel and whichis secured to the s okes C denotes a casing embodied in t e steering in which the wheelie included.- Ip-pi'actice it is desired that two heaters H constructed in accordance Th marginal portions ofthe layer 1 are defined by theioutstanding strips 2 preferably. of rubberwith the inner walls of said stnpof a thichiess ordepth of substantially three-'eighths of an inch;

Snug y fitting withln the field defined by the strips 2 is a layer 3 of ashestosor other non conductiveand heat resisting material, said layer 3 being preferably of a thickness of substantially one-eighthof an mch. Resting upon the layer 3 are the transverscl dlsposcd heating units U. The units are so spaced one from the other as to ositlon the heater H is in applied position. The

when

Mwill' have sufiicient frictional;- contact. with k the rim R to prevent theheeter H slipping.

7 resting upon an end portion of the layer 3.

The ad acent, end strip 2 is provided with the openings 8 through which the conductors b are disposed for electrical connection with the posts 6 and said conductors b are maintained in electrical connection with the post 6 through the medium of the removable clampingl caps or nuts 9. Each of the nuts or caps 9 is provided in its outer face with the groove 10 to receive a suitable implement to facilitate the application or removal thereof. As is particularly illustrated in F i g. 1 the conductors b are continued along a spoke S to a controlling switch 11. Coacting with the switch 11 are the conductors 12 leading from a suitable source of electrical energy and preferably the magneto of an automobile or other conveyance. As disclosed in Fig. 1 the switch 11 co-acts with the conductors b of each'of the heating units and it is intended that the switch 11 be of such a character as topermit each of the heaters H to operate in unison or one independently of the other.

. The space surrounding the heating units U is provided with a filler 14 preferably of Tnsbestos fiber and 'nverlying" the. heating units nd the fillei; 14 and snugly fitting within t e field defined by the str1ps'2 is a second layer i5 of asbestosl'or other insulating and heat resisting material. The layer 15 is also substantiall one-eighth of an inch in thickness. At t is time it might be well to state that it. is preferred that the heating units U be substantially one-sixtccnth of an inch thick. overlying the layer 15 and the outer face of the strips 2 is a covering A preferably embodying two superimposed laminations, the inner lamination 16 being preferably of canvas and the outer lamination 17 preferably of leather.

The cover A is secured to the strips 2 by the rows of stitching 18 and which rows of stilching are also directed through the inner layer 1. It is alsodcsired thatthe rows of stitching 19 be disposed through the cover A and the layers 1, 3, and 15 at points inter mcdiatc'the heating units U and extending in a direction longitudinally of the heater' I I. These latter rows of stitching serve to hold the cover and the several layers in assembled relation.

Disp sed through the longitudinal marginal portion of the heater are the eyelets 20 through which is adapted to he threaded the lacing 21 for securing the heater H in applied position upon the rim R or to facilitate its removal. It is preferred that the meeting edges of the heater H or the lacing 21' be arranged inside of the rim R.

From the foregoing. description it is thought to be obvious that an electrical heater constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without nmterially departing from the principle and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my iniention in practice except as hereinafter claimed.
